    Pinhole glasses consist of precision, lightweight perforated plastic lenses. In detail, there are a series of pinhole-sized perforations that fill an opaque sheet of plastic in place of each lens. And each perforation allows only a very narrow beam of light to pass through and reach the eye. This design greatly reduces the size of confusion circle on the retina, bringing clear images and improving depth perception.

    While ensuring the sharpness of the image, pinhole glasses can further relax the eyes. This additional effect occurs because those pinhole glasses are smaller than the size of the eye's normal pupil. Eye strain and even headache are common after a long period of computer work. Similar situation may also occur while reading in very poor light. These pinhole glasses can help the eyes reduce tension, and this effect can be immediately felt.
